An efficient video compression system based on LSK encoder

Abstract

Video compression means reducing the size of data in order to represent the digital video images. The main goal of our research is to develop a robust video compression system. To begin with, wavelet decomposition is applied to the I-frame and using the Listless SPECK (LSK) algorithm, the resulting coefficients are quantized. Subsequently, an Adaptive Rood Search with Spatio-Temporal Correlation technique (ARS-ST) is employed for motion estimation. Finally, the difference between the original P-frame and the predicted P-frame is computed, which is referred as the residual. The proposed video compression technique is assessed by several videos and the effectiveness of compression is evaluated by measuring the PSNR values for the compression results. © 2011 Springer-Verlag.
